Q.
Which of the following alkanes cannot be produced by Kolbe electrolysis of sodium or potassium salts of carboxylic acids?
Hydrocarbons
Solution:
In Kolbe’s electrolysis, the alkane is formed when an aqueous solution of $Na$ or $K$ salt of carboxylic acid is electrolysed. The alkane formed has, two or more carbon atoms. This method can be used to prepare alkanes with even number of carbon atoms.
